Advancing the Art of Structural Fatigue Analysis
In the early 90's, Battelle scientists recognized the need for a reliable stress analysis methodology that would address the known problems encountered in conventional finite element analysis procedures for welded joints or geometric discontinuities within structures. Consequently, Battelle created, developed and validated a new patent pending methodology known as the Verity® mesh-insensitive structural stress methodology. Although initially viewed as "too good to be true" or "too simple to possibly work," Verity® has now been validated by leading industry experts across a broad array of industries.
 
A few years ago, Battelle scientists also recognized the need for a robust, efficient and physically sound multi-axial cycle counting and fatigue life assessment method. Consequently , Battelle developed and validated a new innovative Battelle patented methodology known as PDMR. PDMR allows engineers to assess fatigue lives for welded as well as non-welded structures under general, variable amplitude, multi-axial fatigue loading histories. PDMR has been validated by leading industry experts across a broad array of industries, ranging from heavy machinery to offshore/marine industries, and it has been adopted by BV as a new guidance for fatigue design of off-shore structures.

Benefits realized from use of Verity®
Cost:
  • Ability to optimize material usage.
  • Significant reduction in CAE and FEA modeling time.
  • Lower development costs by minimizing fatigue testing requirements.
  • Ability to inspect and test components against fatigue criteria should lower "classification" or regulatory compliance costs.

Performance:

  • Ability to optimize material performance and engineering designs.
  • Reduce tendency to over-design to account for uncertainty can result in lighter structures.

Quality:

  • "Mesh-Insensitivity" eliminates variability/uncertainty of current procedures.
  • Fatigue life predictions that are accurate (reduce failures, warranty claims, etc.)
  • Easy to use and automate; compatible with existing FEA software.
